Review on GHz High Frequency Ground Block by Jamar Gow
Works with power through coaxial cable
I can't comment on its grounding ability as it's difficult to test, but I can confirm one important feature: it passes electricity. I have a preamp connected to an antenna (Vinegard 200) with a USB power supply inside, with this ground block in between. The amplifier operates on power supplied through the coaxial cable and through this ground block.
- Good product for the price
- Minor issues
